A new study examined the new fossils of an "incredibly" long-armed dinosaur nicknamed "Horrible Hands" and demonstrated that the dinosaur had a prominent hunchback, was omnivorous, and had features that prevented it from sinking into wet ground.
Lead author Yuong-Nam Lee told Discovery News that the dinosaur had a peculiar humpbacked form with a duckbill-like skull and it measured 36 feet long, weighed 14,000 pounds and lived 70 million years ago.
The fossils were originally located at the Nemegt Formation in Mongolia.
"Horrible Hands" was not so horrible as its arms are the longest on record for any two-legged animal, paleontologists suspected that the dinosaur could have been a ferocious predator on par with meat-loving hunters like T. rex and Allosaurus.
The study is published in the journal Nature.
